Progress.
I’ve not seen white seats with black door panels before.
My ‘71 Barracuda vert came white on white. Panels badly chalked.
I bought a black set years ago with plan to change to black interior.
The '72-74 manuals on PDF's appear to be scarce as hens teeth. I had a thread here and another forum looking for one for free. I searched in vain. Yes there are places where you can buy and download them; some versions folks complain the watermarks added by the vendor obscure the images...
It’s been 40 years since I tried to put my cover on.
I slid it on the seat first then snapped it to the trim.
I actually left it attached to the seat same as the original owner. Probably why the clips are broken from the top retracting.
The '70 Parts Book is also lacking in the hardware call out for the valance (called "shield) and valance insert (simply called "panel").
Truly an oddity...
And here is a snipet I put together from the '70 service manual. It confirms the push pins and calls them retainers.
Interesting that the manuals do not use the term valance and valance insert, and instead refers to them as "air shield" and "air shield trim", respectively.
